SPECIFICATION forming part of Letters Patent No. 23,160, dated' July 20,1880. Y" Application filed May 6,1880. (No model.)

iron, the length and width of which are niade to conform to the widthand length of the paddle-box, and admit of clcsing the doors.

rIhe operating-pistons B B are connected, two in number, at each end ofthe blades, near 5o the upper and lower corners \hereof,by means ofwristpin joints C C. The pistons pass through stuffing-boxes in theplate of the boxes and the sides of the ship, and are connected at theirinner ends to the piston-rods of the 55 engines of the ship, bv whichaction is given to the blades, causing them to work alternately backwardand forward, following` each other in succession, so that while one entof the blades are retained in a given position against Cio the sides ofthe paddle-boxes their opposite ends move in a contrary direction acrossthe tube, forcing out or expelling the water with great velocity fromone end o the tube or the other, and thereby motion is imparted to the65 vessel.

The blades or paddles may be set iu a horizontal, vertical, or inclinedposition, and the piston ot' the blades made to conform to theconstruction ot the ship or vessel, and be em- 7 ployed with or withoutthe paddle-boxes, the link-connections of the ends of the pistons withthe ends of the blades being such as to admit of the free movement atthe end of the stroke, as described.

Having thus described my invention, what 'I claim, and desire to secureby Letters -Patent, is-

The rectangular paddle-box A, provided with doors B B and man-hole b, incombination with the blade D and Vpistons B B', all constructed andarranged to operate as and for the purposes specified. v

In testimony that I claim the foregoing I have hereunto set my hand andseal, this Batt To all whom it may concern:

Be itlinown that l, FERDINAND VON LEICHT,

u of San Francisco, in the county of San Frani'- cisco and State ofCalifornia have invented a i 5 new and useful Means of Iropelhng Ships,ot'

which the following` is a specification. My invention consists of arectangular box l or paddle-house attached to each side ot' the shipbelow the water-line thereof, in which is Io placed a ilat blade orpaddle worked by horizontal transverse pistons connected to each end ofthe paddles in an alternate reciprocal manner by direct connections withthe engines. The ends ot' the pistons are connected tothe i i 5 paddlesby wrist-pin joints, so that each end of the paddle or bladeis workedbackward and Y forward in an alternate manner and independi ent of theopposite end, which forces or draws -I the water against. thc sidesofthe ship or pad- 2o dle-boxes, and thus the shipis propelled, all o apear.

Iteferrin g to the accompanying drawings, 25 Figure 1 is a sectionalplan view. Fig. 2 is a sectional side view.

rIlhe rectancular boxes or tubes A, I construct of iron, securelyattached to the sides of the ship below the water-line. 'I hey are pro-30 vided with water-tight doorsB B, which, when open, set in a ledgemade in the extended porl tion ot' the iron frame of which the boxes arecomposed. Each ot' these doors is providek with a curved arm, ct, whichextends inwardly, 3 5 passino' through stuffing-boxes, and when the idoors are wide open and set close within the beino to close the tubes orboxes and make l 4 no them water tight, in case of disarrangeinent o theblades, when the wateris drawn out through 1 an inside man-hole, b, intothe hold of the vesf Y sel or conducted away by means of a hose,

- 1 pi e, or other conductor. y

` 45 The blades D, I construct of flat plates of day of April, 1880.
